Abstract: 1,170,522. Nuclear magnetic resonance spectrometers. VARIAN ASSOCIATES. Feb.3, 1967 [Feb. 14, 1966], No.5387/67. Heading G1N. In a nuclear magnetic resonance spectrometer having two resonance channels, one of lower frequency for observing the weak resonance of C<SP>13</SP> or N<SP>15</SP> nuclei and the other of higher frequency for controlling the resonance condition of the spectrometer by means of the resonance of different nuclei such as F<SP>19</SP> or H<SP>1</SP>, both resonance signals are picked up by a common coil 9 which forms part of a double-tuned circuit 25 having respective higher frequency and lower frequency loops. As shown in Fig. 1, a transmitting coil 8 is connected to a double-tuned circuit 10 similar to circuit 25. The lower frequency loops L.F. contain wave traps 11 to reject the higher frequency of the control channel. The coils 8, 9 are shown crossed, but coaxial coils may be used. The output of the lower frequency (analysis channel) transmitter 36, Fig. 5, is connected to terminal 16 and the output of the higher frequency (control channel) transmitter 41 is connected to terminal 21. Terminal 27 is connected through amplifier 37 and phase detector 38 to a recorder 39. Terminal 26 is connected to the control channel which adjusts the polarizing field and/or the frequencies of the transmitters 36, 41. Alternative ways of coupling the terminals 21, 26 to the double-tuned circuits are described with reference to Figs.2 and 3 (not shown). In an embodiment described with reference to Fig.4 (not shown), only one coil (31) is provided which serves for transmitting and receiving, the coil being part of a double-tuned circuit (32) to which the transmitters are capacitively coupled and the receivers are directly coupled. In a modification of this embodiment, Fig.4A (not shown), the analysis channel transmitter is connected to a separate coil (8) which may be coaxial with, or crossed with respect to, the other coil (31), and which may or may not form part of a tuned circuit. The two types of nuclei may be in a common sample tube 3, or may be in separate concentric compartments. The sample tube may be rotated.

Title: Process for the production of fatty alcohols
Inventor: EISENLOHR KARL-HEINZ
IPC: C07C29/149
Filed: 1961-02-15
Abstract: A fatty alcohol is produced by the catalytic hydrogenation of a fatty acid, or a derivative thereof, at 200-350 DEG C. and 200-700 atm. in the presence of a known catalyst for the hydrogenation of carboxylic acid esters to alcohols, the material to be hydrogenated being continuously introduced into a reaction medium which consists almost entirely of the desired alcohol which has been saturated with hydrogen, so that the material is distributed uniformly almost instantaneously throughout a large excess of the alcohol. Fatty acid derivatives which may be used as starting materials are esters, anhydrides and lactones of fatty acids, oxyfatty acids with or without esterified hydroxy groups and free or esterified ketofatty acids. The preferred starting material is a symmetrical ester of the fatty acid, e.g. n-heptyl-n-heptoate or lauryl laurate.  The preferred catalysts are copper/chromium oxide catalysts which may be modified by additional components, e.g. barium. Examples are given of the hydrogenation of coconut oil fatty oil acids, palm-kernel fatty acid and tallow oil fatty acids.
